Handroanthus impetiginosus is a tree species with ecological and economic potential. Despite that, in the Brazilian market, its wood is heavily exploited in the illegal trade. Therefore, studies on genetic diversity are necessary in order to propose strategies for conservation of this species. Thus, the aim of this study was to select Inter Simple Sequence Repeat (ISSR) primers for genetic diversity studies applied to the forest population of H. impetiginosus. For this, 30 ISSR molecular primers were tested in 30 individuals, evaluating the total number of loci, polymorphism rate and polymorphic information content, as well as marker index and resolving power. Eight primers were selected for having a better amplification pattern, which provided 62 loci. The polymorphic information content of the primers ranged from 0.34 to 0.49, while the marker index (MI) averaged 3.20, with resolving power (RP) of 2.40, Nei’s diversity (He) of 0.35 and Shannon index (I) of 0.52. The results show that the primers UBC 807, 809, 818, 824, 857, 860, 873 and 881 are efficient for quantifying the genetic diversity of H. impetiginosus. These results can contribute to supporting strategies aimed at the conservation of this species and selection of parent trees.

“…Although Mimosa is one of the largest genera from Mimosoideae (Barneby, 1991), there are few population genetics studies for species of this genus (Moreira et al, 2011;Pramual et al, 2011;Arruda et al, 2019;Araújo et al, 2020;Morales et al, 2020), and none of these previous studies used SNP markers. Nevertheless, genetic diversity has been estimated using markers such as RAPD (Mimosa pigra; Pramual et al, 2011), AFLP (Mimosa subser.…”

Intraspecific genetic variation plays a fundamental role in maintaining the evolutionary potential of wild populations. Hence, the assessment of genetic diversity patterns becomes essential to guide biodiversity conservation policies, particularly for threatened species. To inform management strategies for conservation of Mimosa catharinensis – a narrow endemic, critically endangered plant species – we identified 1,497 unlinked SNP markers derived from a reduced representation sequencing method (i.e., double digest restriction site associated DNA sequencing, or ddRADseq). This set of molecular markers was employed to assess intrapopulation genetic parameters and the demographic history of one extremely small population of M. catharinensis (N=33) located in the Brazilian Atlantic Forest. Contrary to what is expected for narrow endemic and threatened species with small population sizes, we observed a moderate level of genetic diversity for M. catharinensis [uHE(0%missing data)=0.205, 95% CI (0.160, 0.250); uHE(30%missing data)=0.233, 95% CI (0.174, 0.292)]. Interestingly, M. catharinensis, which is a lianescent shrub with no indication of seed production for at least two decades, presented high levels of outcrossing [t(0%missing data)=0.883, SE±0.0483; t(30%missing data)=0.909, SE±0.011] and an apparent absence of inbreeding [F(0%missing data)=−0.145, 95% CI (−0.189, −0.101); F(30%missing data)=−0.105, 95% CI (−0.199, −0.011)]. However, the reconstruction of demographic history of M. catharinensis indicated that the population should be suffered a recent bottleneck. Our population genomic study tackles a central issue in evolution and conservation biology and we expect that it will be useful to help safeguard the remaining genetic diversity reported for this unique genetic resource.

“…Mimosa caesalpiniifolia Benth. (Fabaceae), popularly known in Portuguese as 'sabiá' or 'sansão docampo', is a forest species native to the Northeast region of Brazil (Dutra et al, 2020), with multiple potentials of use, such as, recomposition of degraded areas (Alves et al, 2004), folk medicine (Albuquerque et al, 2007), production of posts, stakes, lampposts, firewood and coal (Pinto et al, 2016;Avelino et al, 2018;Araujo & Paes, 2018;Araujo et al, 2020;Lins et al, 2020), landscaping and construction of living fences (Araujo & Paes, 2018).…”

“…Given the silvicultural importance of M. caesalpiniifolia, the demand for its seeds is expected to increase in the near future (Araujo et al, 2020). Thus, the present study aimed to determine the viability of Mimosa caesalpiniifolia seeds from unripe and ripe fruits stored at different temperatures (ambient, 10 ºC, 0 ºC and -21 ºC).…”

The maintenance of seed viability during storage is influenced by several factors related to the species and to the environment. This work aimed to determine the viability of Mimosa caesalpiniifolia seeds from unripe and ripe fruits stored at different temperatures (ambient, 10 ºC, 0 ºC and -21 ºC). For this, the germination performance of the seeds was evaluated at 0, 3, 6 and 12 months of storage. The experimental design was completely randomized, with four replicates of 25 seeds per treatment. The variables evaluated were: number of germinated seeds, number of hard seeds, number of unviable seeds and number of normal seedlings. The storage potential of M. caesalpiniifolia seeds depends on the fruit maturity stage. Seeds from unripe fruits without drying do not tolerate storage. Seeds from unripe fruits with drying at 15% water content maintain viability, for 12 months, when stored at a temperature of 10 °C. Seeds from ripe fruits without drying maintain viability, for 12 months, when stored at temperatures of 0 °C and 10 °C.
